Fabrication And Comparative Study Of Horizontal And Vertical Electrospun Protein-Polysaccharide Nanofiber Biomaterials, Ashley Rivera-Galleti

Theses and Dissertations

The use of biocompatible and biodegradable composite materials for biomedical applications has attracted the attention of many researchers in the past few years. In this study, we fabricated nanofibers of silk fibroin and cellulose and its derivatives to amalgamate their unique properties into a single material. The production of these nanofibers via electrospinning is of particular interest, and whereas several studies have been done on normal nanofibers, the formation of branched nanofibers is an exciting area not currently explored. Blend solutions are formed by dissolving silk and cellulose/cellulose acetate in formic acid separately and mixing to achieve the desired ratios. …

Praxis Of Jose Marti: Politico Literary Discourse And Agency For Independence Movement, Yishan Lea

All Faculty Scholarship for the College of Education and Professional Studies

This article explores Jose Marti’s political mobilization in general and extrapolates Marti’s praxis specifically. A multifold analysis is conducted as follows: first, the analysis explores the narrative of Jose Marti regarding the development of his consciousness and his role in changing the historical trajectory of Cuba; second, the analysis examines Marti’s political praxis in engaging with the geopolitical semiotic field and mobilizing Cuban cultural communities for the Cuban War of Independence.

Making It Just In Time: Author-Creator Matsumoto Taiyō, Natsume Fusanosuke, Jon Holt, Teppei Fukuda

World Languages and Literatures Faculty Publications and Presentations

Translated by Jon Holt and Teppei Fukuda

The first time I can remember encountering Matsumoto Taiyō’s work was probably when he released his short story collection, Blue Spring (Aoi haru - Matsumoto Taiyō tanpenshū [stories published from 1990 to 1993; Shōgakukan, 1993]). All of the stories concern a bunch of young dudes -- full of desires, frustrations, and violent tendencies -- and no chance they can ever get past those things. I thought to myself at that time, “Ah, I bet this stuff means a lot to readers in their teens, but they don’t really do anything for me.” …

In the light of the urgency raised by the COVID-19 pandemic, global investment in wildlife virology is likely to increase, and new surveillance programmes will identify hundreds of novel viruses that might someday pose a threat to humans. To support the extensive task of laboratory characterization, scientists may increasingly rely on data-driven rubrics or machine learning models that learn from known zoonoses to identify which animal pathogens could someday pose a threat to global health. We synthesize the findings of an interdisciplinary workshop on zoonotic risk technologies to answer the following questions. What are the prerequisites, in terms of open …

Rapid Morphologic Changes To Microglial Cells And Upregulation Of Mixed Microglial Activation State Markers Induced By P2x7 Receptor Stimulation And Increased Intraocular Pressure, Keith E. Campagno, Wennan Lu, Assraa Jassim, Farraj Albalawi, Aurora Cenaj, Huen-Yee Tso, Sophia P. Clark, Puttipong Sripinun, Néstor Más Gómez, Claire H. Mitchell

Health & Biomedical Sciences Faculty Publications

Background

The identification of endogenous signals that lead to microglial activation is a key step in understanding neuroinflammatory cascades. As ATP release accompanies mechanical strain to neural tissue, and as the P2X7 receptor for ATP is expressed on microglial cells, we examined the morphological and molecular consequences of P2X7 receptor stimulation in vivo and in vitro and investigated the contribution of the P2X7 receptor in a model of increased intraocular pressure (IOP).

Methods

In vivo experiments involved intravitreal injections and both transient and sustained elevation of IOP. In vitro experiments were performed on isolated mouse retinal and brain microglial cells. …

Police Officers’ Best Friend?: An Exploratory Analysis Of The Effect Of Service Dogs On Perceived Organizational Support In Policing, Kenneth M. Quick, Eric L. Piza

Publications and Research

This study explored the effectiveness of a novel technique for police departments to support their officers and promote wellness: the use of service dogs. We evaluated officer perceptions in two mid-sized, municipal police departments that have wellness programs with a service dog that is permanently assigned to a full-time police officer handler: Groton and Naugatuck, Connecticut. We assessed 6 factors believed to influence police officer wellness including: operational and organizational stress using the Police Stress Questionnaire (McCreary & Thompson, 2006); topical stressors including those related to the COVID-19 pandemic, police use of force and community relations, and police reform efforts; …

Adapting Tropical Forages To Low-Fertility Soils, Idupulapati M. Rao

IGC Proceedings (1977-2023)

Tropical forages growing in low-fertility acid soils usually increase the amount of dry matter partitioned to roots at the expense of shoot growth, but substantially different adaptive attributes to such soils have been found, both between and within species. By possessing the C₄ pathway of photosynthesis, grasses are more efficient than legumes in using N, Ca, and P, whereas legume roots are more efficient in extracting nutrients from low-fertility soils. Phosphorus uptake efficiency (mg of P uptake in shoot biomass per unit root length) of the legume Arachis pintoi is several times higher than that of the grass Brachiaria …

Adaptation Of Forage Species To Drought, D. J. Barker, J. R. Caradus

IGC Proceedings (1977-2023)

Variability in rainfall is the single greatest cause of variation in forage production for a given site. Current climate scenarios predict future annual rainfall to decrease at some geographic regions. The intensity of future rainfall is also predicted to increase at other regions, with the expectation of greater variability in soil moisture. The adaptation of forage species to drought is an issue that is likely to remain with us into the future.

Precise definitions are critical to water relations work, and imprecise use of terms has complicated comparisons of some studies on plant response to drought. Drought is a purely …

Spittlebugs: Bioecology, Host Plant Resistance And Advances In Ipm, José R. Valério, C. Cardona, D. C. Peck, G. Sotelo

IGC Proceedings (1977-2023)

Several species and genera of spittlebugs (Homoptera: Cercopidae) are economic pests of grasses in tropical America. These insects compete with grazing animals by reducing forage availability and quality. They may cause serious losses on millions of hectares of improved pastures based on cultivars of several species of Brachiaria (signal grasses). Except for the cultivar Marandu, most of the available commercial cultivars of Brachiaria are susceptible to spittlebugs. In spite of their economic importance, much research need to be done yet. Such insect-plant system encompasses a diverse group of spittlebug species, a diverse group of forage grass species, which are under …

Representing Africa In The ‘Coming To America’ Films, Samuel K. Bonsu, Delphine Godefroit-Winkel

Markets, Globalization & Development Review

Through an interpretive analysis of the two Eddie Murphy films "Coming to America" (CTA) and "Coming 2 America", spaced nearly 30 years apart, this review essay underscores the persistence of Orientalist Othering of Africa. The negative images of Africa that are so engrained in people have been facilitated in significant part by a strategic, but perhaps unconscious, effort to socialize audiences into an identity construction process that casts Africans as inferior. Despite attempts at favorable depictions of Africa, these processes continue to play out.

When We See Us: Coming 2 America And The Intricacies Of Black Representation And Diasporic Conversation, Terri Bowles

Markets, Globalization & Development Review

This is a review essay of the film Coming 2 America (2021) by Craig Brewer, a follow-up to the 1988 comedy classic Coming to America , which stars Eddie Murphy as a newly crowned African king confronted with shifting family dynamics and evolving challenges to his royal authority. The review examines the cultural space occupying the 30 years that separate the first film and its sequel, and interrogates the structures of popular film and comedy that situate representational discourses of gender and diasporic Black representation.

Grassland Plant Diseases: Management And Control, S. Chakraborty

IGC Proceedings (1977-2023)

Grasslands cover 40% of the earth’s surface and support animal-based industries; maintain soil cover, watersheds and biodiversity; sequester atmospheric carbon for storage in the soil; and provide tourism and leisure income. Diseases continue to decrease herbage and seed yield and reduce nutritive value and palatability of grasslands to impact on animal health and productivity but realistic data on loss are hard to find. Although principles of disease management remain the same, strategies used in crop protection can not be directly applied to grasslands due to differences in heterogeneity, population size, density and spatial distribution and population continuity. Low per hectare …

Soil Carbon And Nitrogen Dynamics After Pasture Installation In The Amazon Region, C. C. Cerri, M. Bernoux, C. E. P. Cerri

IGC Proceedings (1977-2023)

The objective of this paper is to present the soil carbon (C) and nitrogen (N) dynamics in a chronosequence made of a forest and pastures of different ages established in a Oxisol in the Western Brazilian Amazon Basin. The results of soil Carbon and Nitrogen stocks and gases fluxes were discussed. Stable ¹³C isotopic technique was used to calculate for a determinate age of pasture installation, the proportion of soil C remaining from the forest system and the proportion of soil C introduced by the grasses of the pasture system. The C lost from the original pool under the …

Micronutrients In Grassland Production, U. C. Gupta, F. A. Monteiro, J. C. Werner

IGC Proceedings (1977-2023)

Micronutrients, also known as trace minerals, which chiefly include boron (B), molybdenum (Mo), copper (Cu), zinc (Zn), manganese (Mn) and iron (Fe), are required in extremely small quantities by crops and livestock. Their name, however, is not meant to imply their role is minor. Their lack, e.g., can cause serious crop production problems in forages and health disorders in livestock. This presentation includes the response of forage legumes and grasses to micronutrients, their deficiency and sufficiency levels in forages and their sufficiency levels in livestock. Forage legumes are more responsive to micronutrients, particularly B and Mo, than grasses. There are …

Pasture Seed Production Technology In Brazil, Ronaldo Pereira De Andrade

IGC Proceedings (1977-2023)

Efficient and low cost production systems, which rely on the use of cultivated pastures, are the basis of beef and milk production in Brazil. The success of these pasture-based systems would not be possible without the support of an aggressive and dynamic pasture seed production sector to supply the internal demand, which is estimated to be around 90000 tons per year. The market is dominated by grass species and among them, Brachiaria. brizantha cv. Marandu accounts for more than 80% of the total seed volume in the market. Seed production systems in Brazil vary from highly specialized to opportunistic accordingly …

Judgement Bias In Miniature Donkeys: Conditioning Factors And Personality Links, Maria Pinto, Francisco Javier Navas González, Camie Heleski, Amy Mclean

Animal and Food Sciences Faculty Publications

Expectation-related bias may configure individuals’ perception of their surrounding environment and of the elements present in it. This study aimed to determine the repercussions of environmental (weather elements) or subject-inherent factors (sex, age, or personality features) on judgment bias. A cognitive bias test was performed in eight Miniature jennies and four jacks. Test comprised habituation, training and testing phases during which subjects were trained on how to complete the test and scored based on their latency to approach an ambiguous stimulus. A questionnaire evaluating eleven personality features was parallelly completed by three caretakers, five operators and two care assistants to …

Meeting The Changing Need For Herbage Seed Quality Assurance In The 21st Century, D. S. Loch, K. G. Boyce

IGC Proceedings (1977-2023)

Quality assurance is a key element in the herbage seed supply chain. The measurement and management of seed quality is discussed in terms of its four main parameters - genetic, physical, vital, and phytosanitary quality - which provide information on the expected performance of herbage seed when sown in the field. During the past century, seed quality management systems have evolved in response to national and regional differences in economic development, crop characteristics, merit testing, and the demands of international trade. The pace of change in the management of seed quality assurance has intensified in developed countries over the past …

Novel Grasses And Legumes Germplam: Advances And Perspectives For Tropical Zones, E. A. Pizarro

IGC Proceedings (1977-2023)

It has been the aim, in the present article, to bring together as much as possible scientific evidence and experience in new available germplasm for tropical zones.

The economic importance of the Brachiaria, Paspalum and Pennisetum grasses is well established. New germplasm has become available since 1980. This paper reviews evaluations of Brachiaria accessions in humid lowlands and savannas of tropical America. The selection criteria need to be revised. Also, it is necessary to expose the new material as early as possible to farmers in order to select new germplasm with high chances of adoption.

Within the genus Paspalum …

Temperate Forage Grass-Legume Mixtures: Advances And Perspectives, A. S. Laidlaw, N. Teuber

IGC Proceedings (1977-2023)

The paper summarises some of the advances which have been made a) in increasing understanding of the grass-legume association, especially grass-white clover, so that the association can be more predictably exploited and b) in overcoming limitations in the use of such mixtures. The contribution which forage legumes make to the N economy of mixtures is reviewed with estimates approaching 400 kg N ha^-1 for some. Uptake by grass of legume- derived N (N transfer) reduces soil mineral N levels and increases the proportion of fixed N in the total legume N relative to legume monoculture. Although N transfer also …

Trust, Power, And Transformation In The Prison Classroom, Fran Fairbairn

Journal of Prison Education and Reentry (2014-2023)

This article does three things. First, it asks a new question about transformative education, namely ‘what is the role of power and trust in the decision of whether to transform one’s meaning scheme in the face of new information or whether to simply reject the new information?’ Secondly, it develops a five-stage model which elaborates on the role of this decision in transformative learning.[1] Finally, it uses grounded-theory and the five-stage model to argue that power and trust play an important role in facilitating transformative learning.

No Cell For The Soul: Prison, Philosophy And Bernard Stiegler - A Short Appreciation, Rod Earle

Journal of Prison Education and Reentry (2014-2023)

Bernard Stiegler was a French philosopher who served 5 years in prison for a series of bank robberies committed in his youth. He died in August 2020, aged just 68, a professor celebrated in the highest ranks of continental philosophy. Stiegler subsequently published over 30 books, at the core of which is the series tellingly gathered under the title ‘Time and Technics’. His essay, ‘How I became a philosopher’, convinced me he, and it, should be on every prison philosophy course. In this article I outline why, as a convict criminologist, I feel an affinity with Stiegler’s project.

‘…In The Secret Of One’S Life’: Bernard Stiegler And Philosophy In The Intimacy Of His Prison Cell, Anna Kouppanou

Journal of Prison Education and Reentry (2014-2023)

In his book, Acting Out, philosopher Bernard Stiegler confesses that the question once posed to him by Marianne Alphant − namely, ‘How does one become a philosopher in the intimacy and secret of one’s life?’ threw him ‘into an embarrassing position’, mainly because Stiegler became a philosopher in the intimacy of his prison cell. There is no question that from Socrates to Antonio Gramsci, there have been philosophers who have suffered shorter or longer periods of imprisonment, but this was mainly because of their philosophy – their individuated way of being and thinking. In Bernard Stiegler’s case, it appears …
